Location of battery in 1997 Mercedes Sl500
So the battery died and I got a friend to help me recharge it. We couldn't find the battery though, so we googled its location. It appears to be on the top left side, under the hood, but it looks like it has a cover which needs to be unscrewed. However due to heavy snowfall and severe cold we gave up for the night. Is the location of the battery accurate? And if so, is there anything else needed to be done after we unscrew the cover? Thanks
